Why is an ecosystem with higher levels of biodiversity more stable than an ecosystem with lower levels of biodiversity quizlet?

The allele frequencies or large populations are more stable because there is greater variability and they are less affected by changes.

Why is an ecosystem with higher levels of biodiversity more stable than an ecosystem with lower levels of biodiversity?

Generally speaking, greater species diversity (alpha diversity) leads to greater ecosystem stability. This is termed the “diversity–stability hypothesis.” An ecosystem that has a greater number of species is more likely to withstand a disturbance than an ecosystem of the same size with a lower number of species.

Why is an ecosystem with a higher biodiversity more stable?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

Why is an ecosystem with greater biodiversity more resilient than an ecosystem with less biodiversity?

Explain why an ecosystem with greater biodiversity is more resilient then an ecosystem with less biodiversity. AN ecosystem with greater biodiversity has more organisms that preform similar functions so it can recover faster from disturbances than an ecosystem with fewer organisms.

How does biodiversity affect the stability of an ecosystem quizlet?

How does biodiversity affect the stability of an ecosystem? Having a number of different organisms increases the stability of an ecosystem, because a change in the population of one organism will have less effect on the population of an organism that depends on it.

What makes an ecosystem with high biodiversity low biodiversity?

When an ecosystem has high biodiversity it is always more stable than an ecosystem that has low biodiversity. … Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.

How does biodiversity affect the sustainability of an ecosystem?

The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.

Which ecosystem is most stable?

Oceans is stable ecosystems since it stays unchanged over the long term. Various natural geological and anthropogenic forces build and damage mountains, deserts and forests but oceans have remained stable over the long history of the Earth.

What makes ecosystem stable?

Stability Important

The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem’s ability to remain stable when confronted with a disturbance. Resilience is the speed at which an ecosystem recovers from a disturbance.

Why is stability important in an ecosystem?

Ecosystem stability is an important corollary of sustainability. Over time, the structure and function of a healthy ecosystem should remain relatively stable, even in the face of disturbance. If a stress or disturbance does alter the ecosystem is should be able to bounce back quickly.

Why are ecosystems with more biodiversity healthier and more resilient?

This research showed that diverse communities are more stable because they exhibit resistance during extreme climate events.” … Instead, resistance to change clearly superseded resilience as the main mechanism by which biodiversity helps to preserve ecosystem stability in the face of climatic extremes, he said.

Why does the biodiversity of an ecosystem affect its resilience?

Diversity-Stability Theory

Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.

Why are some ecosystems more resilient than others?

He stated that ecosystem stability increased as the number of interactions (complexity) between the different species within the ecosystem also increased. … This elasticity means that ecosystem properties, such as changes in nutrient flow or the number of species, are more resilient due to changes in species composition.

When might an increase in biodiversity lead to a decrease in the stability of an ecosystem?

An increase in biodiversity usually leads to an increased stability, but in the case of an invasive species it would lead to a decreased stability.

Why is biodiversity important to ecosystems quizlet?

Biodiversity is the variety of life in the world or in a particular habitat or ecosystem. Biodiversity is important because it provides us with Natural Resources (Food, Water, Wood, etc.) Natural Services (Pest Control, Air and Water Purification, etc.) and of course, Aesthetic Pleasure.

Does the loss of biodiversity alter the stability of ecosystems and the integrity of ecosystems?

Loss of biodiversity undermines the ability of ecosystems to function effectively and efficiently and thus undermines nature’s ability to support a healthy environment. This is particularly important in a changing climate in which loss of biodiversity reduces nature’s resilience to change.
